Mahr Micromar 44 EWR Digital Inside Micrometer

Mahr Micromar 44 EWR Digital Inside Micrometer The Mahr Micromar 44 EWR is a precision-grade digital inside micrometer engineered for accurate, repeatable internal diameter measurement across a broad range of industrial applications. Designed for precise measurement in through holes, blind holes, and centering shoulders, this self-centering micrometer delivers the high accuracy and repeatability demanded by machinists, engineers, and quality control professionals. The self-centering measuring head features three laterally positioned anvils offset at 120° intervals, ensuring consistent, stable contact with the bore wall on every measurement. Carbide-tipped anvils (from 12 mm) provide exceptional wear resistance for long-term precision use, while the hardened mineral glass display pane offers superior protection against scratching and breakage in demanding workshop environments. The threaded connection system allows for fast, tool-free measuring head changes, and the lightweight anodized aluminum head housing (from 40 mm) reduces operator fatigue during extended use. With Digimatic, Opto RS-232C, and USB data interfaces, the 44 EWR integrates seamlessly into digital measurement and SPC documentation workflows. Key Features Self-Centering 3-Anvil Measuring Head - Three anvils offset at 3 × 120° deliver automatic centering and stable, repeatable contact in any bore geometry. Carbide-Tipped Anvils for Extended Tool Life - Carbide tips (from 12 mm) resist wear and ensure long-term measurement accuracy across high-volume inspection tasks IP52 Environmental Protection - Rated IP52 for resistance to dust ingress and splashing water, providing reliable performance on the shop floor. Multi-Interface Digital Output - Digimatic, Opto RS-232C, and USB interfaces enable direct data transfer to SPC software, data loggers, and measurement systems. High-Contrast Digital Display - Large, easy-to-read digits support fast, error-free readings even in low-light or high-production environments. Interchangeable Measuring Heads - Threaded head connection allows quick head swaps across multiple measurement ranges, maximizing instrument versatility.
